A suffocating, shadow-drenched aura wraps the pet, with dim, pulsing embers flickering beneath a veil of creeping darkness. The model gains a subtle vignette and black particle wisps that trail as it moves, evoking the feeling of weight and inevitable pull.
Ability: Permanently gains an additional 6–30 XP per second (value rolls on application). This bonus stacks additively with other XP-per-second sources and is active at all times.
How to Obtain
Headless Horseman pet exclusive - Granted through chaotic haunting ability
Chaotic mutation system - One of four random mutations applied when Headless Horseman haunts level 50 pets
40-minute cycle - Headless Horseman haunts random level 50 pet every 40 minutes, resetting to level 1
Spooky Egg exclusive - Headless Horseman only obtainable from Spooky Egg with 2% hatch chance
Best Way to Get Dreadbound Mutation
Hatch Headless Horseman from the Spooky Egg during the Ghoul Garden Event, then place it to haunt your collection every ~40 minutes. Prepare several level 50 pets without mutations to maximize attempts; each haunt resets a target pet to level 1 and applies one chaotic mutation at random (25% chance for Dreadbound).
Pro Tips
Target pets you plan to actively level. The flat XP/s from Dreadbound accelerates early- and mid-level grinds disproportionately well.
Roll until you land higher XP values (closer to 30). Since the value is fixed on application, duplicates are worth considering if you want a better roll.
Chain haunts by staging multiple level 50 candidates. Rotate through them to avoid downtime between Headless Horseman cycles.
Pairs nicely with percentage-based XP boosters from other sources to compound leveling speed.
Community Secrets
Players report the visual darkness subtly intensifies with higher XP rolls—purely cosmetic but a neat tell.
Great pick for pets you constantly reset or prestige; the passive XP cushions frequent restarts.
Early-game power leveler—can replace some idle XP farm setups entirely on support pets.
